Previously, the code assumed\n'stream_status' could be null, but did not handle the case where it was\nactually null. This could lead to a null pointer dereference.\n\nReported by smatch:\ndrivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_resource.c:3784 planes_changed_for_existing_stream() error: we previously assumed 'stream_status' could be null (see line 3774)"
